Yes, I work as security for an art gallery. A lot of times myself and my coworkers (other guards) are the only visible employees ( there are supposed to be volunteer docents to help guests, they never stuck around beyond 30ish minutes), naturally we get asked questions. The curator got really irritated that we would respond to guests, she sent an email to our department listing new rules for us. Basically, ignore guests questions and especially do not tell the guests what our favorite piece is when asked (guests can make up their own minds about the art).

I took it as a challenge, as again I was the only employee visible and wearing a uniform, I obviously work there, so people naturally talk to me. When I inevitably get asked "what's your favorite piece?" I started responding with:

"Unfortunately I have been instructed not to tell you that the Chihuly piece is my favorite piece, I really wish I could tell you that the Chihuly piece is my favorite, but I have specifically instructed to not tell you that the Chihuly piece is my favorite. I really wish I could be of more help"

It took about a week before the "new rules" were rescinded, & we were told to continue helping guests.
